redis-cluster集群搭建

环境：centos7.6

云主机：192.168.1.129  192.168.1.128   192.168.1.127

软件版本：redis-5.0.8.tar.gz

1，在3台同时解压，编译

yum -y install gcc

tar -xf redis-5.0.8.tar.gz

cd redis-5.0.8  && make  && cd src/  && make install

2，maste：192.168.1.129

mv redis-5.0.8 /usr/local/redis

cp /usr/local/redis/redis.conf /data/redis/6380/conf/

cp /usr/local/redis/redis.conf /data/redis/6381/conf/

3，修改配置文件，密码先不要配置，配置完集群在设置密码，最后2行先不要

    第一个redis 6380文件

第二个redis 6381 文件

把文件拷贝到另外2台机器

scp -r /data 192.168.1.127:/
scp -r /data 192.168.1.128:/

4,启动6个redis，每台执行

redis-server /data/redis/6380/conf/redis.conf

redis-server /data/redis/6381/conf/redis.conf

5，开始启动集群，这个是5.0以后集群启动的方式，和以前的不同，下面的截图是其他地方的

redis-cli --cluster create 192.168.1.129:6380 192.168.1.128:6380 192.168.1.127:6380 192.168.1.129:6381 192.168.1.128:6381 192.168.1.127:6381 --cluster-replicas 1

查看集群是否成功

redis-cli --cluster check 192.168.1.129:6380 -a '1ZdqlgWBfw'

[[e-mail] ~]# redis-cli --cluster check 192.168.1.129:6380 -a '1ZdqlgWBfw'

集群搭建完毕，开始设置密码，6个节点都要设置，下面拿一个举例

redis-cli  -h 192.168.1.127 -p 6381

[[e-mail] ~]# redis-cli  -h 192.168.1.127 -p 6381
192.168.1.127:6381> config set masterauth 1ZdqlgWBfw
OK
192.168.1.127:6381> config set requirepass 1ZdqlgWBfw
OK
192.168.1.127:6381> auth 1ZdqlgWBfw
OK
192.168.1.127:6381> config rewrite
OK
192.168.1.127:6381> exit

最后设置完后再次查看集群状态

[[e-mail] ~]# redis-cli --cluster check 192.168.1.129:6380 -a '1ZdqlgWBfw'
